The structure and control methods of existing distribution networks are planned assuming unidirectional power flows. The amount of generation connected to distribution networks is, however, constantly increasing which ...

The large number of practical applications involving digital images has motivated a significant interest towards restoration solutions that improve the visual quality of the data under the presence of various acquisition ...

With various remote sensing technologies to aid Earth Observation, radar-based imaging is one of them gaining major interests due to advances in its imaging techniques in form of syn-thetic aperture radar (SAR) and ...

Radio-frequency identification (RFID) makes use radio waves to track objects equipped with electronic transponders, commonly known as tags. In passive RFID systems, the tags are remotely powered and they are composed of ...

Personal positioning is a challenging topic in the area of navigation mainly because of the cost, size and power consumption constraints imposed on the hardware. Satellite based positioning techniques can meet the requirements ...

Smart metering is currently implemented in many countries. The change from traditional metering is significant and impacts many of the Distribution system operator´s (DSO’s) activities. This dissertation aims to provide a ...

The ever-increasing complexity of radio devices is phenomenon fed by the ever-growing demands of users for higher data rates and more services from a single device. Today, advanced cellular phones have transceivers for ...

Multipath remains a dominant source of ranging errors in any Global Navigation Satellite System (GNSS), such as the Global Positioning System (GPS) or the developing European satellite navigation system Galileo. Multipath ...

IP is often seen as the “lingua franca” of modern communication. It provides interoperability across various heterogeneous link layer technologies and enables access to a rich set of services available in the Internet. As ...

Energy and environment are inseparable, since the production and use of energy always affects the environment. Current energy production relies on nonrenewable energy sources such as oil, coal and natural gas. However, the ...

Software systems are becoming complex entities with an increasing diffusion into many new domains. A complex software system requires more resources to develop and maintain. Some domains demand continuous operation like ...

Frequency spectrum is the scarce resource. From mobile operator’s point of view, efficient utilization of the radio resources is needed while providing maximum coverage, and ensuring good quality of service with minimal ...

The demand for mobile data traffic is about to explode and this drives operators to find ways to further increase the offered capacity in their networks. If networks are deployed in the traditional way, this traffic explosion ...

The recent developments in image and video denoising have brought a new generation of filtering algorithms achieving unprecedented restoration quality. This quality mainly follows from exploiting various features of natural ...

Smart grid initiatives around the world show how much the control and protection of distribution networks is expected to change within the next few years. As passive networks with unidirectional power flow evolve into ...

Superconductivity as a phenomenon was discovered over 100 years ago and the first commercially viable materials have been in use for over 50 years. Today, the truly commercial applications in medical imaging and scientific ...

In recent years, three-dimensional television (3D TV) has been broadly considered as the successor to the existing traditional two-dimensional television (2D TV) sets. With its capability of offering a dynamic and immersive ...

The main theme of this thesis is modelling and analysis of biological networks. Measurement data from biological systems is being produced at such a pace that it is impossible to make use of it without computational models ...
